SLAT. A

Application led September 15, 1923. Serial No. 662,896.

To all whom t may concern.'

Be it known that I, JOHN L. LINGL, a citizen of the United States, residing at Bird Island, in the county of Renville and State of Minnesota, have invented certain new and useful Improvements in Slats, of which the following is a specification, reference being had to the accompanying drawings.

This invention relates to certain improvements in slats and has relation more particularly to a device of this general character especially designed and adapted for use in connection with aprons or conveyors of a character associated with manure spreaders and it is an obj ect of the invention to provide a novel and improved slat of this general character formed of a material that will not rot and which is provided with means whereby the same is readily and effectively secured to the side members or chains.

The invention consists in the details of construction and in the combination and arrangement of the several parts of my improved slat whereby certain important advantages are attained and the device rendered simpler, less expensive and otherwise more convenient and advantageous for use,

as will be hereinafter more fully set forth.

The novel features of my invention will hereinafter be definitely claimed.

In order that my invention may be the better understood, I will now proceed to describe the same with reference to the accompanying drawings, wherein Figure 1 is a view in top plan illustrating an apron provided with slats constructed in accordance with an embodiment of my invention;

Figure 2 is an enlarged'fragmentary view in end elevation of one of my improved slats as herein disclosed and in applied position;

Figure 3 is a view in perspective of one of '45 my improved slats as herein disclosed.

As illustrated in the accompanying drawings, C denotes side chains of a character generally employed in connection with manure spreaders or the like and with which are associated the slats S. As herein disclosed the slats S are arranged one in close proximity to the other although it will be understood that they may be positioned lengthwise of the side members or chains C as may be preferred.

Each of the slats S is formed of a single sheet of galvanized metal and comprises an intermediate flat portion l having its longitudinal marginal portions defined by the inwardly directed flanges 2 preferably at right 60 angles to the flat portion 1. The flanges 2 terminate in the inwardly directed plates 4 extending entirely along the flanges 2 and of a length coextensivevin length with the fiat portion l. The plates 4 are in parallelism 05 with the flat portion 1 and have their inner longitudinal margins defined by the upstanding flanges 5 at right angles thereto, said flanges 5 bridging the spaces between the plates 4 and the flat portion 1. 70

In practice, the extremities of the plates 4 are in direct contact with the side members or chains C and the slat is held to said side members or chains C by the bolts 6 and coacting nuts 7. Each of said bolts being dis-` posed through a link 9 and substantially the transverse center of the adjacent end portion of a slat S. The bolts are also preferably applied from below with the associated nut 7 contacting with the flat portion 1 from 80 above. Each of the bolts 6 is also disposed through a block 10 preferably of wood which is interposed between the flanges 5 immediately adjacent to an end of the slat S. The blockl 10 serves to make the end 3 portion of the slat S solid and to particularly facilitate the requisite attachment of an end portion of the slat S with a side member or chain C.

f From the foregoing description it is thought to be obvious that a slat constructed in accordance with my invention is particularly well adapted for use by reason of the convenience and facility with which it may be assembled and operated, and it will also be obvious that my invention is susceptible of some change and modification without departing from the principles and spirit thereof and for this reason I do not wish to be understood as limiting myself to the precise arrangement and formation of the several parts herein shown in carrying out my invention in practice except as hereinafter claimed.

I claim lo In combination with the side members of an apron, a slat interposed therebetween and having its extremities engaged therewith, said slat comprising an intermediate flat portion having its longitudinal marginal 11 portions defined by inwardly disposed and means associated with each side member flanges, said flanges being provided With inand the adjacent end portion of the slat and 10 Wardly directed plates substantially parallel disposed through the block for holding the to the flat portion, the inner margins of the Slat to said side member.

5 plates terminating in fianges bridging the In testimony whereof I hereunto affix my l spaces between the plates and the flat porsignature.

tion, a block interposed between the last named flanges adjacent each end of the Slat, JOHN L. LINGL.
